In restorative dentistry, selecting the right types of dental implants is crucial for achieving optimal results. Each of the different types of dental implants caters to various patient needs and clinical scenarios. Factors like bone structure, health, and specific dental requirements play a role in determining the best option. Here’s a detailed guide on the different kinds of dental implants available:
Fundamental Types of Implants:
Endosteal Implants
Endosteal implants are the most common types of dental implants and are inserted directly into the jawbone. Typically made from titanium or titanium alloys, these implants integrate well with bone tissue.
Benefits
- High Success Rate: These implants are known for their reliability and high success rates.
- Natural Look and Feel: They function like natural teeth, improving chewing and speaking.
- Bone Preservation: They stimulate bone growth and prevent bone loss.
- Durability: With proper care, endosteal implants can last many years, often for a lifetime.
Procedure
- Initial Consultation: Evaluation of oral health and bone density using X-rays or CT scans.
- Implant Placement: Under local anesthesia, the implant is surgically placed into the jawbone.
- Osseointegration: The implant integrates with the bone over several months.
- Abutment Placement: A connector piece is placed on top of the implant.
- Crown Placement: A custom-made crown is attached once healing is complete.
Subperiosteal Implants
Subperiosteal implants are placed under the gum but above the jawbone, making them suitable for patients with insufficient bone height.

Benefits
- Bone Density Accommodation: Ideal for those with inadequate bone height or density.
- Reduced Need for Bone Grafting: Minimizes the need for complex procedures.
- Less Invasive: Typically less invasive compared to bone grafting.
- Effective for Denture Wearers: Provides stability for full or partial dentures.
Procedure
- Initial Assessment: Evaluation of bone structure and oral health.
- Implant Placement: A metal frame is placed on or above the jawbone with posts extending through the gums.
- Healing Period: The gums heal around the frame.
- Attachment of Prosthetic Teeth: Artificial teeth or dentures are attached to the posts.
Zygomatic Implants
Zygomatic implants are anchored into the zygomatic bone (cheekbone), suitable for severe upper jaw bone loss where conventional implants are not feasible.
Benefits
- Suitable for Severe Bone Loss: Effective for patients with significant bone loss in the upper jaw.
- Avoids Extensive Bone Grafting: Reduces the need for extensive procedures.
- Immediate Load Option: Often allows for immediate prosthetic attachment.
- High Success Rate: Reliable even with complex cases.
Procedure
- Preoperative Assessment: Detailed imaging and clinical evaluation.
- Implant Placement: Implants are placed into the zygomatic bone under general anesthesia or sedation.
- Healing Period: A period of healing is required to integrate the implants.
- Prosthetic Attachment: A custom-made prosthetic or dental arch is attached.

Additional Kinds of Dental Implants
Single Tooth Implants
Single tooth implants are designed to replace individual missing teeth. This category
includes:
Immediate Load Implants:
Involved placing the implant and a temporary restoration on the same day.
Delayed Load Implants:
Follows the traditional procedure, which includes a healing period before the restoration.
Mini Implants:
Smaller in diameter used where there’s insufficient bone width. suitable for various
applications.
Multiple Tooth Implants:
Multiple dental implants support prosthetic devices for several or all missing teeth. This
includes:
All-on-4:
Replaces an entire arch with just four implants often with immediate prosthetic attachment.
It often avoids the need for bone grafting and provides immediate results.

All-on-6:
Uses All on 6 implants for enhanced stability and support, providing a full arch of prosthetic teeth.
Comparison of Different Types of Dental Implants
| Feature | Endosteal Implants | Subperiosteal Implants | Zygomatic Implants |
|---|---|---|---|
| Placement Location | In the jawbone directly | On top of the jawbone | In the zygomatic bone |
| Common Material | Titanium or alloys | Titanium or alloys | Titanium or alloys |
| Surgical Procedure | Requires drilling | Metal framework placement | Complex surgery due to zygomatic bone |
| Indications | Common, with adequate bone | Insufficient bone density | Severe upper jaw bone loss |
| Bone Integration | Integrated into bone | Not integrated, sits on top | Integrated into zygomatic bone |
| Treatment Time | Typically 3-6 months | Usually quicker | Longer due to complexity |
| Prosthetic Support | Supports crowns/bridges/dentures | Supports dentures/bridges | Supports crowns/bridges |
FAQs
-
Which type of dental implants is best?
For most patients, Endosteal implants are recommended due to their high success rate and reliability. This type of dental implant integrates well with the bone, providing a strong and durable foundation for replacement teeth.
-
What are the main three types of dental implants?
Endosteal Implants: Placed in the jawbone.
Subperiosteal Implants: Positioned under the gum but above the jawbone.
Zygomatic Implants: Anchored in the cheekbone for severe bone loss. -
What are All-on-4 dental implants?
All-on-4 dental implants involve placing four implants to support a full arch of prosthetic teeth, often with immediate results. This type of dental implant is ideal for patients with significant tooth loss, offering a stable and efficient solution for complete restoration.
-
Which types of dental implants are most commonly used?
Endosteal implants are the most widely used due to their effectiveness. This type of dental implant is placed directly into the jawbone, offering a strong and stable base for artificial teeth, making it the preferred choice for many patients.
-
What is the safest dental implant material?
Titanium is the safest due to its biocompatibility, and it is generally preferred when all natural teeth are missing. While titanium has been trusted in implant dentistry for over half a century, zirconia (ceramic) implants are gaining popularity as a metal-free alternative. Ceramic implants are hypoallergenic, corrosion-resistant, and align well with holistic dentistry practices.
-
What is the cost of dental implants in India?
Costs typically range from ₹25,000 to ₹50,000 per implant, depending on the type and brand.
-
Are dental implants painful?
The dental implant procedure is not painful as it is performed under general or local anesthesia, which numbs the mouth completely. After the procedure, once the anesthesia wears off, patients may experience mild discomfort. However, many find this pain to be less severe than that experienced during a tooth extraction.
